French president Nicolas Sarkozy threatened to pull his country out of the euro if other EU countries, especially Germany, did not agree to help rescue debt-laden Greece.

The French president made his startling threat at a Brussels summit of EU leaders last Friday, at which the deal to bail out Greece was agreed, according to a report in El País newspaper quoting Spanish Prime Minister José Luis Rodríguez Zapatero.

Zapatero revealed details of the French threat at a closed-doors meeting of leaders from his Spanish socialist party on Wednesday.

Sarkozy demanded “a compromise from everyone to support Greece … or France would reconsider its position in the euro,” according to one source cited by El País.
